ATTORNEY UNITED STATES PATENT OFFICE,

BENJAMIN L. CORNELIUS, 0F HUTCHINSON, KANSAS.

OIL-BURNER.

To (17/ whom, it may concern:

Be it known thatI, BENJAMIN L. Conunnos, a citizen of the United States, residing at Hutchinson, in the county of Reno an b'tate of Kansas, have invented certain new and useful Improvements in Oil-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to oil burners, and more particularly to a device of that class wherein oil is atomized by and mixed with air or steam to render it effective for heating purposes.

it is the principal object of the )re. eut invention to provide a burner of this type wherein the air or steam, and oil, will mix at the most advantageous point relative to the burner tip for securing highest efficiency, and whereby the oil may be prevented from draining back into the air or steam supply conduit, should there be an over supply of the oil.

It is also an object of the invention to provide a burner which is simple and economical in construction, easy to install and simple and dependable in operation.

In accomplishing these ob 'ects I have provided the improved detai s of structure hereinafter more fully described and illustrated in the accompanying drawings, wherein Figure I is a longitudinal, vertical section of an oil burner constructed according to my invention. Fig. II is a perspective View of the tip end of the burner.

Referring more in detail to the parts: 1 designates a fitting or head having a channel 2 opening vertically therethrough and through a nipple 3 formed integral therewith and adapted for receiving the oil sup ply pipe 4. The channel 2 opens into a central, horizontal and forwardly directed channel 5, which in turn opens into a chamber 6 in the forward portion of neck 7 of the head. Threaded into the mouth of channel 5 is a tube 8 which extends forwardly through the. chamber 6 and outwardly a short distance from the head, the outer end of said tube being provided with Specification of Letters Patent.

Serial No. 877,214.

a plurality of ports, each having a purpose presently set forth.

Extending rearwardly from head 1 is a tip 10 having a valve stem channel concentric with the conduit channel 5, and threaded into the head is a stem 11 having a hand wheel 12 on its free end and having a needle valve point 13 projected into the tube 8 and into the port 14 in a valve block 15 which is fixed within the tube.

It is apparent that flow of oil through tube 8 may be regulated by the needle valve in the ordinary manner.

Threaded into the chamber 6 in the neck 7 is a drum 16 which surrounds the oil tube 8 to form an annular chamber 17 for the reception of air or steam from the conduit 18 which latter opens through a neck 19, and carries an air and steam supply pipe 20. The drum 16 is longer than the tube 8 and has an oft-set shoulder 21 near the end against which a diaphragm 22 is seated said diaphragm having a central aperture provided with screw threads for receiving the threaded end of the oil tube, so that it may be screwed on said tube and bear tightly against the drum shoulder 21,

thereby requiring oil or steam to escape first into the oil tube and then out through the burner tip. Threaded into the open end of drum 16 is a tip 23, preferably having its spherical end provided with a horizontal cross slot 24 slightly below its center and inclined downwardly as shown.

In using the device, the head may be assembled with the supply pipe in an ordinary stove or furnace. To start the burner under a cold boiler, it is first necessary to generate steam for the operation of the burner; compressed air may be forced through the pipe 20 so that it may enter the oil tube, and mix with oil delivered thereto from the oil supply pipe, the flow of oil into the tube being regulated by the needle valve 8. It is apparent that the air upon en ering the tube 8 will atomize the oil and mix therewith to provide a suitable fuel mixture which is delivered under pressure through the tip slot, and when ignited will burn to supply the desired heat. As soon as steam can be provided, the air is shut off and steam passed through the pipe 20 to perform the function theretofore performed by the compressed air.

Having thus described my invention,what

I claim as new therein and desire to secure by Letters-Patent is:

An oil burner comprising a head having separate oil and atomizing agent conduits, a drum communicating with the atomizin agent conduit and extending from said head, a diaphragm in the end of said drum, a tube communlcating with the oil supply conduit and extending into said drum and through said diaphragm, said tube having imperforate bottom and side portions and having ports in its upper ortion in the rear of the diaphragm, and aving a valve near the head for controlling flow of oil from the su ply sourceto the apertured porl5 tion thereo, and a removable tip on the outer end of said druin into which fuel is delivered from said inner tube, substantially as set forth.

In testimony whereof I aflix my signature 20 in presence of two witnesses.
